Abstract
A process for production of allyl acetate includes steps of reacting acetic acid 3, oxygen 1 and propylene 2 in the presence of a catalyst in an oxidation reactor 5 to form allyl acetate and water; separating the unreacted acetic acid by a distillation column 9; and recovering an acetic acid-containing liquid which contains acetic acid and returning the acetic acid-containing liquid to the oxidation reactor 5 via an acetic acid-water evaporator 4, the process further including a heating step of heating a process liquid which contains the acetic acid-containing liquid to a temperature of 80 to 250° C. by a heater.
Claims7
A process for producing allyl acetate, comprising:
- reacting acetic acid, oxygen, and propylene in the presence of a catalyst in a reactor to produce allyl acetate and water;
- separating the unreacted acetic acid by a distillation column;
- recovering an acetic acid-containing liquid which contains acetic acid and returning the acetic acid-containing liquid to the reactor via an acetic acid-water evaporator;
- and
- heating a process liquid which contains the acetic acid-containing liquid to a temperature of 80 to 250° C. by a heater to polymerize unsaturated compounds,
- wherein the process liquid is the bottom liquid of the acetic acid-water evaporator.
